I think D and E? cuz 15 x 6 is 90
Answer:
Around (1.5,-4) because the two lines intersect around there
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
The function you use to find the angle will depend on the other information given. Regardless, finding the angle may involve the inverse sine <em>function</em>, not the inverse sine <em>ratio</em>.
_____
If you know the leg adjacent as well as the leg opposite, the inverse <em>tangent</em> function will be an appropriate choice.
So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
Answer:
X = 7
Step-by-step explanation:
180=90+4x+6+8x
84=12x
7=x
